From Daniel Magasanik, Melbourne, Australia
Impey doesn’t mention another reason for caution in contacting aliens, even if they are assumed to be benevolent. They might freely make technologies available to us that are far more advanced than our own, thinking that they could only help us. They may assume that we don’t suffer from the dysfunction and conflicts that plague our (so-called) civilisation and that we wouldn’t put such technologies to destructive uses.
